Volume and Area

This week, our class have been learning about area and volume of shapes. Area is the measurement for a 2D shape, how much is in the 2D shape( length x width ). Volume is the measurement of a 3D shape, how much is in the 3D shape( length x width x height ).

Volume= bh. bh= base x height. Base is length x width, because the base is like a 2D shape. Base x height is the same as length x width.

5th grade Cat Tien trip


Last week, 5th grade went to Cat Tien, which is a forest really near Dao Tien. This trip was for learning about sustainability and it was a case study. Case study is when we go there and learn directly, not from the internet.

1.What did you do at the Moon Bear Center?  

We went to the moon bear center,where they help the bears that was stuck in small cage and got their bile taken from them, and they help the bears to become bears and survive only in the wild. We went to the bear play are ,which the moon bear is still in their own cage so its safe, and what we had to do was to spread and hide the their foods around the place to encourage them to find their own food, like the way they do in the wild. Some of us got some peanut butter and spread around the area which was trees mainly. Some of us got fruits and hid them on trees and leaf and bush, some on the ground. It was great fun, then the teachers told us it was time to release the bears so we got out of that area and went to a high place to look at the bears, finding their food. While watching, we were journaling in our books. Then we got the professional to come and answer some of our question about moon bears and sustainability.

2.What did you like and what was an unexpected surprise at Cat Tien?  What was something you’d never seen before?  What was your favorite moment?

I like Cat Tien because the food was decent and the rooms are clean, also because the way we connect with nature, and how at night it’s not like the city,  it gives me a ‘wild life’ feel. There’s no motorbike and no cars going around. No city lights, and how its so silent and how bright and pretty the stars are.

For me the unexpected surprise thing was that this was the place where last year in my old school went as a trip, also the food there, I thought is not that good because it is in the forest but it turns out to be really good.

I have never seen a weasel before and now that I went to Cat Tien, I did. I didn’t really see the whole body of the weasel because it was so quick climbing on the trees that I couldn’t see it properly.

My favourite moment is when I went on the night safari because I have never ever gone through a forest at pitch dark night and seeing all those animal is super amazing. The wind was cool and sometimes we came to places that the trees curved in making me feel like I’m in a tree cave.

3.How does Cat Tien connect to our unit about sustainability?

Well, Cat Tien was a very sustainability place because how they think about having a good enjoyable places for us and how it is eco-friendly, how it is also design for wild life out there.

Sustainability is when we use something and it never run outs. For example, wood, we could use wood and once we use them, it turns into something and then it keeps going on.  And it will grow more of it so it makes it sustainable.

Cat Tien is saving endangered wild animals like moon bears and they are trying to keep the bears from being extinct. There are only a few moon bears left in the world and some countries doesn’t even have them and Viet Nam has moon bears and if Viet Nam don’t save them, the moon bears could really become extinct. And also they’re saving the gibbons and pygmy loris.

Innovation Activity in 5th Grade

This week in 5th grade, we had an activity which is call ‘hack your classroom’. Which is basically making something new to help our classroom and improve our school. We had 3 option to choose from, 3D printing, virtual reality and littleBits. I choose 3D printing because I think it is cool and easy to work with. Also it’s creative when you start doing it.

My project is about how we could keep our important post-it note, not to fly away, when it’s un-sticky anymore. I choose this decision because I always loose important note and it’s useless when a post-it note is not sticky anymore, and that’s how I came up with this idea. Also I think that this project is really easy to make because it’s basically a binder with tiny pockets, all of that stuff is really easy to print also.

The idea is to have unstick post-it note to not get lose and we lost our reminders, information or to-do list.



 True or False?

  1. This shape is a quadrilateral.

True. This shape is a quadrilateral because it has 4 sides.

2. This shape is a trapezoid.

False. This shape is not a trapezoid because it doesn’t all the rectangle attributes.

3. This shape is a rhombus.

False. This shape is also not a rhombus because, like before, it doesn’t have all the attributes.

4.This shape is a parallelogram.

True. This shape is a parallelogram because all the opposite sides are parallel.

5. This shape is a rectangle.

True. This is a rectangle because it has all the attributes.


Our class book report

What book are we reading in class together?                                                                                                           In 5EJ, we been reading a really good book called ‘The Lemonade War’.

What is the conflict between the two main characters?

The conflict between the 2 main character is the brother, Evan, got mad at Jesse, the sister, for skipping 3rd grades to 4th grade( when Evan is also moving to 4th grade) he think’s it’s embarrassed. At first, was fine with Jesse is skipping grades but then he realized that Jesse is in the same classroom as him.

What would YOU do if you were Jesse, and coming home from the beach?

If I was Jesse, coming home from the beach, after I reach home, I would explain to Evan what I did and say sorry. I wouldn’t lie because it’s just going to make matter worse and he’s going to find out anyways.

What would YOU do if you were Evan, and coming home from your friend’s pool?

If I was Evan, coming home from my friend’s home, I would phone the guy that took Jesse’s money and ask him to bring it back. After that I would put it back in her lock box and would apologizes afterwards. This situation was even worser than when Jesse put nasty things in his lemonade. I would become a good brother after everything.

Any other thoughts you have in reflection about this book

  • First thought, I think it that Jesse nasty plans where not as horrible as Evan’s plan because Jesse loss over 2 bucks and Evan only loss 40 dollars.
  • Second thought, Evan actually really miss Jesse because he couldn’t have fun with his friends when Jesse’s gone to the beach.

Waht I observed in math about multiplying decimals

In our class so far, we have been study in math about multiplying decimals and we started this yesterday. Today, we had a really fun time learning this with cubes. Mrs Johnson teaches us about multiplying decimals with decimals and decimals with a whole number. I’m going to tell you about what I’ve learn so far.

I learnt on Tuesday with Mrs Johnson, how to multiply decimals with decimals, using the traditional way. So basically, we just simply take away the decimals like it’s not there, multiply it like normal and then add in the decimal place. To know we should add the decimal we take the 2 decimals number you just use to get your answer, count how many place the decimals are on each on and add the decimals place onto your answer. If you don’t get this than I’ll give a example:


Take away the decimals which is 02×05=10

Then add in the decimals by v=counting how many decimals place are in 0.2 and 0.5. Which is 2 decimals places together because imagine if 0.2 was 02, the decimals in 02 will be behind the 2. Then from there we move the decimals to the middle of 0 and 2 so we get the same as 0.2. So that’s 1 place, do the same with 0.5 and together it’s 2 place. Add the decimals onto the answer, which is 10, 2 place so it’s going to be 0.10.

And always know that when you multiply a decimal with a decimals, it becomes smaller. A DECIMALS NUMBER IS THE OPPOSITE OF A WHOLE NUMBER. So that’s what I learn on Tuesday.

Today, as I told you, we had a super fun lesson with cubes. We sat in a circle on the carpet and Mrs Johnson out cubes and the carpet floor and gave us a multiple in decimals and we have to show the answer by cubes. It turns out that multiplying a tenths with a thousandths is a lot harder than I think because it takes up a lot of the cubes and we actually have to use the whole class to make the answer. To multiply a decimal and a decimals, we have to overlap the shapes. And the overlapping part is our answer. If we have a decimals with a whole number like 0.2×2 is two groups of 0.2. And best, after that we get to play with the cubes for a few minutes. Me and my friends made a big tower.

Here’s some of the pictures:

Our research reflection

What have you done so far in this inquiry journey?
We have been doing researches on a topic that we want and it was something that was curious and
we don't know the answer to. 
We have been research on KidsInfoBites because it's a good way to find out the answer to our 
topic, we don't search it on the internet because when we do then 
it's going to come up with a bunch of different web site and not only it's a lot, it have 
different answer to. Also, some of them is incorrect and it's a bad web site.
Some people ask other people who is expert at it like for example we could ask Mr Papaseit, or 
teachers that we know that teaches about it or knows a lot of information on that topic.
Also we could go to the library to borrow some books about it.
What have been a challenge so far?
The challenge so far for me is about our topic like if I'm more interesting in this than that. 
For example if there's 2 topic that I don't know what to choose from black space or Big Bang. 
I'm interested in space but I'm not sure really what to choose.
Another challenge I find is finding our resources. If they don't have the answer I'm looking for
than that's hard.
What are you excited about? 
I'm excited about writing about the topic because I really like space. And sometimes the answer 
could be really interested.
What do you wonder? 
I always wonder about if you get pull into a black hole then, what would it be like? Would it be
another universe or will you just be stuck in the darkness forever? And also how is a black hole


Our amazing race took place on Wednesday and this was really tired but it was very fun and it teaches me about self-reliance. At first, we was about to take the taxi around district 1 but then everyone knows that it’s not safe at Viet Nam for kids to be taking the taxi alone, so we end up walking around district 1 for the amazing race.

We had  in total 12 teams and my teams were yellow team. The team were black team, yellow team, pink team, green team, orange team, patterned red team, red team, patterned green team, patterned blue team,  light blue team, dark blue team and purple team. Every team had at least 5 student and one chaperone. My team had Anna, David, Matthew, Yoyo and me  .  All the teacher was in charge of the challenge and each challenge have at least 2 teacher.

On our amazing race, we had some mistake and risk that we made, but it really teaches us about self-reliance and dealing with everyday situation. Our biggest risk is when we went on the wrong road, trying to reach Takashimaya and we end up walking double distance.

We start the race at the school and our first challenge  ran across the soccer pitch and find  the envelope that leads us to the big blue top..The big blue top is where we found our team bag, inside the bag is our final destination but the tricky part is it has the lock to it. The number on the lock is the number of the envelope that we received after we finish a challenge. Then we took the school van to the place we suppose to be doing our first challenge. Our team didn’t made it to the finishing line. The funniest thing is we were on our 2nd last challenge( which is Takashimaya), Matthew accidentally open then locked bag.

During this race, it teaches me a lot of responsibilities when w’re alone on ourself. And I hope you guys know what we did on that day.

Pictures of Buu Long Trip

Here are some of the picture:    🙂

So that’s our trip


5th grade Buu Long trip??

Yesterday, 5th grade went to Buu Long, a adventure trip. We were soooo lucky we went this year because  the other 5th grades haven’t gone for 4 years now…?. The teacher that went with us was Mrs Johnson, Mrs Kim, Mr Edward, Ms Chi, Ms Rayle, Ms Tram, Mr Chesterman and Dr Keller.Buu Long is located in the North of  Ho Chi Minh City. We went with a company called Phat Tire. There were 7 activities in total, there were Zip Lining, Abseiling, Rock Climbing, blind block, Maze, the circle game and the number game. My favourite activity was Zip Lining because all we have to do is  sit and relax.

The activity I found most challenging was the abseiling because I’ve never tried it before and some people got hurt, scared or had fallen down the water…?. I did overcome this challenge, because my friend, Isabel, said it was really fun and I saw other people did it really easily so I wanted to do it too.

I did have some risk along the way though.One risk was when doing rock climbing, I nearly reached the red line but I  scrapped myself on the rock and then fell down but not a lot. I decide to keep going on because if I don’t then I’ve wasted my time climbing up.

I would like for you to know that you should always wear long pants(NOT PE PANTS) because you end up get lot’s of scratch if you don’t… Some people got scratch.

Here’s some picture for our trip:
